@Slv7, If you go back to the Unwinder thread has another command to check the alternate bus. One person with eVGA card who as getting a "invalid" response is now getting a "not invalid" response. http://forums.guru3d.com/showthread.php?t=380513&page=2

Slv7, Unwinder MSI Afterburner developments with NCP4206 voltage regulator allow unlocking reference card voltage to 1.3: http://forums.guru3d.com/showpost.php?p=4638716&postcount=22 Will be interesting if this can be done with the Classy to unlock further than 1.5 ....

Famich,

If you have a Classy then you want the modded Classified bios, correct?

It's the one at your overclocking forum that many Classified owners are using.

EVGA 780 - Classified vbios pack - 'OC edition v03' - see attachments

I think Svl7 mentioned the classy vbios mod has 440w? at default settings. If you go back a few pages he talks about why he left it at 130%.

Edge3903,

You need 5 posts to have download access. The Classified vbios pack was modded from Original '3A' Classified Normal and LN2 bios.

Dentnu,

Does that happen if you change the "power management" setting in the Nvidia driver game profile from "adaptive" to "performance"?

In terms of how well it enables a card to overclock, its doubtful, but you could always flash one and then the other and compare.

I think in his case it might help since he has a Classified. Svl7 increased the Power target to 130%, not to mention anything else in the bios specific to the Classified hardware.

Thanks for clearing that up. I was sure exactly how PrecisionX handled the Power Target %'s relative to voltage settings.

Yeah, true, but interestingly the board ID in the vbios is the same as used in the reference card, so I say the classified vbios will work on reference cards as well, but there's no point in doing so, it still won't be possible to go above 1.21V with the reference card.

That makes sense .... my concern would be the increased Power Target in PrecisionX and whether damage can occur with Extreme benching on non-classified cards.

@pharma, Did you under-clock the memory or is that stock? I wonder how high can GPU go. I'd love to see 1.3 on Titan though.

Stock memory on 780 Classifieds is 6008 and I overclocked to 7718. As far as how high depends on benchmark, cooling and "GPU" lottery, though eVGA does pick these GPU's to achieve very high frequencies.

@svl7,

Thought you would like to see 780 Classified results using Svl7 TI Classified bios - Nothing extreme yet

i7 3960x @ 4.9Ghz --- GTX 780 Classified --- 1306.5/7718 --- +274/+855 --- P11349 --- Air

ASIC 67.1

Nvidia Driver 326.41

Power Target: 95%

Temp Target: 94c

Thanks again for your work and solutions with evga Modded vbios.

Now on another note, would it be possible for me to flash my Gigabyte 780 with the EVGA modded bios set for LN2?

I know the Classified has a new VRM module to handle high voltages and a bigger PCB with additional caps which probably come into play and add additional safety when performing extreme benchmarking. The Classified bios could have settings related to expected hardware tolerances.

EVGA 780 classified added to the first post. Let me know if everything is alright, can't test it myself. Please post a Nvidia Inspector screenshot showing the OC part.

Svl7,

I'll post screenshot in few moments after I flash. Than again for your work on the vbios!

Edit: NvInspector Screenshot below of LN2 bios. Correction: Power Target max is now 130%.

Sure, send me the originals and I'll take a look at it when I find time.

PM sent ....

Thanks

SvI7,

Would you consider a vbios for people using a 780 Classified on DICE or LN2 with higher power target?

EVGA 780 - SC ACX - 80.10.3A.00.80 added to the first post, still don't have a card to test it myself so please let me know whether it works fine. A screenshot of nvidia inspector (showing the OC stuff) for visual confirmation would be nice.

Is this new eVGA bios you modded? This vbios works excellent with Classifieds ... in my opinion the best date. Keep up the good work! Below is the NVidia inspector info:
